Look in snyders I think they sell a neoprene packing set that lasts a lot longer but try tightening the nut a little more regular greasing helps. Yamaha sells a paraffin base snowmobile grease that doesn’t mix with water great for water pumps
Thanks I'll try the new Snyders next.
I greased and tightened it up today and will see how long that lasts. Seems the old guy just likes pissing on my garage floor from time to time. I have card board on the floor most of the time but seems when I don't that's when it leaks.
